I
do think that Google has done a lot of work to objectively add value to the results page of most search queries (eg pulling data straight from websites like Wikipedia, giving better page previews, etc).
However they are an ad company - and they ultimately benefit from blurring the line between an advertisement and a "real" result. I do feel like it is harder to find certain types of results as a "power user" though, and it feels like the quality of results rapidly drops off after the first page. I am not sure if the fault lies with Google or with spammy websites hacking the SEO.
I wish Google had something like duckduckgo.com/lite (also ddg.gg/lite) for the atypical "power user." It's nothing but text results. I find it really useful for certain types of searches and when you don't want to be bothered by how "busy" the Google search results page has become.
